Warning can be a bit much

[update: added my own art.]

A green coyote general lives alone in his home, in retirement, with maids and butlers at his calling but.. He's lonely and bored. So he calls you, his rival over to have some fun.

You and him are old friends during your childhood, but because of the war a few years ago you both fought against each other, and were a match for each other, and years later today, you both still hate each other but the friendship still exists deep down below the depths. Even if you can't stand his face.
